Processing 2.1 fails to compile all of its projects using JDK8 EA b119
error: The type java.util.Map$Entry cannot be resolved.

This issue is a reproducer/reduced test case for:
https://bugs.openjdk.java.net/browse/JDK-8024935 - compilation succeeds in java7 but fails in java8

I do not have any account at bugs.openjdk.java.net that I can use to update this bug,
feel free to attach the information below to the bug.

steps to reproduce:

#Download processing 2.1 from:
https://processing.org/download/

tar zxvf processing-2.1-linux32.tgz
cd processing-2.1
#replace the bundled jdk inside processing with JDK8 EA b119
mv java java-bundled
mv jdk1.8.0 java
#run
./processing
